I have not, but that is a good idea.
I have learned that if I get what appears to be blue-green algae that running the pump more helps reduce it. When I was running the linear diaphragm pumps with not nearly as much turn over rate I had more problems with the bluegreen algae blooms. With this pump if I start to see it I increase the run time and that seems to help.
I relate it to what the sewage pond aeration pumps do. They really agitate those with rapid turnover so the nutrients are oxidized. That may be the wrong type of thinking, but it appears to me mixing the water more helps the water rid itself of at least some parts of excess nutrients.
